为进行动态测试系统的误差溯源研究,以一种差动互感电感式位移传感器动态测试系统为研究对象,分析各部分的动态测试特性,分别建立了各环节的单元传递函数与误差函数,并根据全系统动态测试精度理论,建立了该系统总的传递链函数及误差传递”白化”模型。
To research the error tracing of the dynamic measurement, the dynamic measuring system based on differential mutual inductive displacement transducer is studied and the dynamic characteristics internal is analyzed. The element transfer function and error function of each part are obtained. Then, according to the theory of whole-system dynamic measuring accuracy, the total transfer-chain function and error whitening-model are gotten.
